I have no clue as to why they say that. The chronograph doesn't lie and we experienced an immediate increase in velocity with the same projectile and same load.
The Wilson is a guaranteed moa at 1,000 yards using Moly. He's done this for years and we were able to demonstrate that the correctly hBN coated projectiles equaled his accuracy the first day. My error was in reading info from a lot of other users who used more hBN in the process, and by increasing the hBN amount and impact coating time I created a situation as described in the patent. Too much hBN causes erratic results. We also didn't wipe them down properly. We just rolled them in a large Terry towel, and that left too much reside on the bullets.

For us, its increased accuracy, a faster bullet supersonic out beyond 1,000 yards and extended barrel life. If you're nervous, wait a few days till our final results are achieved. Wait till we're at the end conclusion and I'll have a bit more info for you soon.

BTW........ If you can smell the hBN, you're too close to it. Don't sniff the jar! .... and do the BB/projectile separation outside, not in the reloading room. That odor is the sub-micron particles themselves entering your nose. Go back and re-read the sequence at the beginning of this thread in its entirety.

Today is the day, Edge. Weather is going to be about optimum. In the past week we've resolved a lot of case and projectile coating questions.
Back this afternoon.

Here's where we are, Edge. 5 round group minimums.
1/2"moa. We went through both RE15 and 4064 in 1/2gr increments. We suspected that Wilson shooting at sea level with us at 4,000 feet was going to make a difference in his load data, and we were right. 4064 is moa for sure, but the RE15 produced tigher groups. We checked LC against Win brass, but truth be told we think this shiney LC is machine gun brass. We'll be buying some brand new LC next week. Unfotunate that I have around 2,000 LC supposedly once-fired, but now I'm suspicious.

Lat forgot his camera so we'll save that for the 300 and 500 yard shots. Onhce we're truly happy we'll go down the valley for 1,000 yard shooting.
The process ended up being 100 new Sierra MK 175s in the 5" peanut butter jar filled to the 1/3 mark with steel impact coated BBs. Add 2.5gr of hBN and tumble in a Thumler's Tumbler for 3 hours. I know all about all of the posts about amount and dwell time, but after some 350 projectiles coated at varilous amounts, dwell time and sent down range, this is our current opinion. That's not to say we won't mess around with both factors this fall, but at 1/2"moa with a .308 sem-auto I'm not going to complain.

One more session this afternoon, and I'll keep you posted.

Sounds like you've found the right combo, that's great!

I've had better luck with RL15 too. It's what I use exclusively in my bolt gun. I've also found using Lapua brass helps too in the bolt gun. However the Lapua get's chewed up in the semi-auto, so I've switched to LC or Winchester brass.

Have you ever tried Ramshot TAC in your semi-autos? I've found that it works excellent in .223 and .308.

I took my Scout group to our range for a campout Friday night. We had a good time shooting Saturday. I didn't get much shooting in, but one of my friends who works for Tactical Solutions came out and brought his "Goody Case". The boys got to shoot a bunch of suppressed pistols and carbines. They thought that we pretty cool!

I'm looking forward to more of your reports.

We'll resume tests on Saturdy, weather permitting. We're very close now.

Barely 45 degrees, windy.... nutz.
Edge, read this section of the patent.

"This is achieved by the ceramic dry lubricant providing reduced friction and improved bullet seal, reducing vibration or "chatter" of a bullet traveling down the gun barrel. Another advantage is the elimination of gun barrel corrosion. Corrosion or rust can only begin in metal grain boundaries, which, according to the present invention, are filled with the sub-micron sized particles of the ceramic dry lubricant. Anotheradvantage is increased accuracy. This results because the bullet time-to-target is reduced as a result of increased muzzle velocity. Accuracy is increased also due to the reduced stress caused by reduction of friction and heat. Accuracy is also increased as a result of a more consistent bullet seal achieved by the present invention. A final advantage is the inexpensive nature of the present invention, which can be practiced in the field on existing gun barrels."


We're still running dwell time and hBN amounts. We're at the point of changing the procedure to "1/4 of the P-Nut butter jar being the impact coated .177 BBs, 100 175gr projectiles and three (not two) grains of hBN.

I have a confimation enquiry sent to one of the the process originators and should have an answer shorty.
Patience.

And this is the difficult part we're still working on.

"Secondary Ion Mass Spectrometry (SIMS) testing performed on the surfaces of the internal bore of gun barrels shows that the boron nitride powder used in accordance with the present invention results in the ceramic powder particulates beingclearly embedded within the grain boundaries of the metal gun barrel. These test results show that burnishing sub-micron particulate ceramic is effective, and that continued firing of uncoated bullets will continue to experience the advantages of thepresent invention for an extended period of time. Such testing also shows that excessively coating boron nitride powder onto bullets provides erratic results and sometimes no velocity improvement. Thinner coating on the bullets provides more consistentvelocity improvement."


But the question is..... How thin?


Anhd in case you didn't see this one.........

EXAMPLE NO. 1

A 0.308 caliber firearm was loaded with a series of boron nitride powder-coated rounds as well as a series of uncoated rounds. The velocity of the rounds exiting the barrel of the firearm as well as the temperature of the firearm barrel weremeasured in feet per second by a chronograph and in degrees Fahrenheit, respectively, to determine velocity and temperature effects of metal oxide powder implantation by burnishing the internal bore of the barrel with a suitable dry lubricating ceramicparticulate. See FIG. 7 for specific results.

Summary of results

20 uncoated rounds had an average muzzle velocity of 2368 feet per second and a maximum barrel temperature of 120

Wow, what an ordeal!

I'm thinking that I might start experimenting with this process on my .338. I would love to get more velocity out of this round, even more so than my .308's.

What was you SD with the rounds that were coated and how was the accuracy?

No, I'm wondering what your Standard Deviation of Velocity is.

Nice Premier!
